2 Claims. 1

This invention relates to a receptacle of novel construction, theprimary object of which is to provide a means for safely storing andtransporting liquefied gases, such as liquid air, liquid oxygen andliquid nitrogen.

As is well known in this art, to store and transport liquefied gases, itis necessary to retain the latter in an inner metallic containersuspended in the interior of an outer metallic container which has beenor is subjected to high vacuum. The outer surface of the inner containerand the inner surface of the outer container are highly polished toprevent high evaporation through radiation and minimize the possibilityof having gas cling to certain surfaces. It is well understood that highevaporation in vacuum containers is primarily due to heat andconductivity and it is therefore an important object of this inventionto provide a special means for suspending the inner container within theouter container so that a proper spacing of the two containers can beretained at all times during storage and transportation of the liquidgases.

Because of the highly polishedsurfaces of the inner and outer containersas described hereinabove, the brackets secured to the inner and outercontainers for retaining the suspensionlinks must be spot welded to therespective containers. It is another important object of this inventionto provide a special suspension means which will relieve unnecessarystress and strain on the spot welded joints of the attaching brackets.

Another important object of this invention is to provide a suspensionmeans of the character described which also acts as a means forreinforcing the outer container, preventing collapse or breakage of thelatter.

These, together with various ancillary objects and features of theinvention which will later become apparent as the following descriptionproceeds, are attained by the device, a preferred embodiment of whichhas been illustrated, by way of example only, in the accompanyingdrawings, wherein:

Figure 1 is a longitudinal sectional view through the receptacle of theinstant invention;

Figure 2 is a sectional view taken substantially in the plane of sectionline 2-2 of Figure 1;

Figure 3 is a sectional view taken substantially in the plane of sectionline 3-3 of Figure 2;

Figure 4 is a sectional view taken substantially in the plane of sectionline 4-4 of Figure 3;

Figure 5 is a fragmentary side elevatlonal view 2 illustrating themanner of attaching a suspension link to the attaching bracket; and

Figure 6 is a longitudinal sectional view through that portion of thedevice shown in Figure 5.

Specific reference will now be made to the drawings. In the severalviews, in the accompanying drawings and in the following specification,similar reference characters indicate corresponding elements throughout.

Indicated generally at In is an outer, substantially cylindricalmetallic container having an inner, highly polished surface 12 andinwardly struck or indented end walls 14. Welded to the inner surface l2of the outer container in and longitudinally spaced therein arecircumferentially extending U-shaped, T-shaped or L-shaped reinforcingribs 16, the ribs adjacent the side walls l4 being provided withdepending lugs [8 having laterally extending pins 20.

The outer container I0 is subjected to high vacuum and positioned withinthe outer container is substantially cylindrical inner container 22having an outer highly polished wall 24 and bulging or cu uck side walls26. The interior of the container 22 is provided with the conventionalsplash plate or baflie 28 and a porous container 30 for retaining anabsorbent 32 such as carbon.

The container 22 is suspended within the interior of the outer containerID in the following manner. Spot welded to the outer surface of thecontainer 22 adjacentthe corners 34 thereof and struck at a particularradius, as shown clearly in Figure 2, are relatively short plates 36having upstanding lugs 38 carrying laterally extending pins 40. Thesuspension links 42 interconnecting the lugs l8 and 38 comprise a pairof spaced bars 44 and 48, see Figure 6, which straddle the lugs l8 and38, each of the bars being provided adjacent their ends with elongatedslots 48 for receiving the pins 20 and 40. The slots 48 are provided toallow for some adjustment in length of the links 42 and it will be seenthat the inner container 22 is, in effect, suspended at a predetermineddistance from the inner wall of the outer container upon the reinforcingribs l6.

To allow further adjustment of the inner container relative to the outercontainer, certain of the links 42 may be made adjustable in length. Itis preferred that the upper links be made adiustable while the lowerlinks remain rigid for the proper type of suspension, the upperadjustable links being. in eflect, conventional tumbuckles 50, as shownclearly in Figures 1 and 2. It will be understood at this point that theentire 3 receptacle will be provided with an inlet line 62 and an outletline 54 for filling the inner container and removing liquid therefromrespectively.

Thus, it will be seen that a sturdy receptacle is provided in which theinner container 22 is appropriately spaced from the inner wall 01 theouter container to minimize stress andstrain on the spot welded lugs I8and 381 and to reduce to a minimum the evaporation losses due toradiation and conductivity.

In view of the foregoing description taken conjunction with theaccompanying drawings, it is believed that a clear understanding of thedevice will be quite apparent to those skilled in this art. A moredetailed description is accordingly deemed unnecessary.

It is to be understood, however, that even though there is herein shownand described a preferred embodiment of the invention, the same is;susceptible to certain changes fully comprehended by the spirit of theinvention as herein described and within the scope of the appendedclaims.

Having described the invention, what is claimed as new is:

1. In a liquid gas receptacle having inner and outer substantiallycylindrical containers; a means for suspending the inner containerspaced from the outer container comprising spaced circumferentiallyextending reinforcing ribs secured to the inner wall of the outercontainer, platelike lugs secured to the outer wall of the innercontainer adj acent the corners thereof and struck at a radius from thecenter of the inner container, and links interconnecting said ribs andsaid lugs, said ribs including radially extending, depending, plate-likebrackets rigidly secured thereto and having laterally extending pins,said lugs also including laterally extending pins, each of said linksincluding spaced bars straddling said platelike lugs and brackets andholding them nonbrackets rigidly secured thereto and having lat- 4rotatably in a common plane, and elongated slots adjacent the ends ofeach of said links receiving said pins, certain of said links beingadjustable in length.

2. A liquid gas receptacle comprising inner and outer cylindricalcontainers, said outer container having a smooth outer surface, and aplurality of spaced, circumferential ribs welded to its inner surface,said inner container being suspended within said outer container fromcertain of said ribs, plate-like lugs secured to the outer wall of theinner container adjacent the corners thereof and struck at a radius fromthe center of the inner container, links interconnecting said certainribs and said lugs, said certain ribs including radially extending,depending, plate-like erally extending pins, said lugs also includinglaterally extending pins, each of said links including spaced barsstraddling said plate-like lugs and brackets and holding themnon-rotatably in a common plane, and elongated slots adjacent the endsof each of said links receiving said pins.
